Weirdest record defect?

Weirdest record defect - the word sheep in Ella Fitzgerald’s Goody Goody - every version. Or - the sibilance in Slim Gaillards Jump Session - 3 78’s from different times and all have the same. 

I’ve never experienced a pressing defect that showed up every 90 seconds. The ones I’ve heard happen every revolution as the defect comes around again. It may be in the recording itself, although I can’t imagine how it got there. Every 90 seconds?  Strange. 

I wouldn’t say it’s weird as i’ve heard it in very old 70s vinyl and unfortunately had to throw them away. Ye olde PVC infection.

However, i just recently purchased the Cars original album on a 2016 re-issue. From front to back, both sides, there was the background PVC type woosh. Store suggested i clean it which i did.  No dice.

Back she went and swapped it for Black Sabbath’s original 50th anniversary. Haven’t opened it and dropped the needle yet.  Looking forward to it with fingers crossed.

Untame the tiger, excellent album BTW. 

It is rumble generated by the lathe. Many records have this problem. When you have a large subwoofer array this problem is extremely annoying. This is due to old poorly maintained lathes being used to cut lacquers.
